Hi all - our incoming mail keeps dropping over for some reason. I cant find anything in the log files that could be the cause of this (or understand). There is a certificate error but this happens all the time. Some idiot delete a certificate now it has errors and one update re a firewall will not install. These problems occur all the time but at least twice a week the incoming mail stops. My ISP assures me that they have a relay on but when the mail drops the emails are bounced back with a delivery issue. Is it my 2008 server that is bouncing them back?
I have attached a log file and the error. I need help with the certificate as well if possible.
